Gamblers know American Roulette as the “double-zero roulette.” In 1800, some greedy establishments added the thirty-eighth sector to French Roulette—00—to get even more profit. Currently, the house edge in American Roulette for almost all bets is 5.26%. It is almost twice as much as the house edge in European Roulette. Double zero roulette wheel The double zero roulette wheel has 38 slots, with two zeros alongside every number from 1 to 36. The zeros are numbered 0 and 00 so players will be able to differentiate between the two. Both zeros are coloured green, and the other numbers will alternate between being black and red.

Suggestions and Betting Advice
The two main types of bets are inside and outside bets. The inside bets can be used to represent specific areas around the roulette wheel, whereas outside bets represent deliberately randomized sections of the wheel.
Typically the maximum bet limit is much higher for outside bets than it is for inside bets. This is for a few reasons. Firstly, outside bets are guaranteed to lose in the long term, so casinos want you to bet big. Inside bets can represent specific sectors of the roulette wheel, and all roulette system or technique that legtimate beat roulette in the long-term are based on bets on wheel sectors.
General Tips
See roulette tips and free roulette system that works for much more detailed professional advice. But below are basic tips specifically regarding bets and the table:
- Play on European Single 0 wheels where possible: The house edge is double on the American 00 wheel. In other words, you have a much better chance of profiting on European single 0 wheels.
- Consider the frequency at which wins will occur, so you don’t make bets that may take you hours to have a win: For example, if you are playing for fun and bet on a single number, you can expect to win on 1 in 35 spins. This is about an hour of play and it will be tedious if you are only playing for fun. You could of course bet on many individual numnbers, but this can be costly if your numbers don’t spin.
- Consider the time of day when you play: during peak periods, the wheel may spin as infrequently as once every 5 minutes. This can detract from the fun of playing.

Introduction
Double Ball Roulette plays like regular roulette, except with two balls. I first saw the game at the 2013 Global Gaming Expo and later at the Tropicana in Las Vegas on February 18, 2014. The Tropicana uses a double-zero wheel.
Later, in November, 2016, I noticed it at an Internet casino using Felt software. Felt uses a single-zero wheel.
You might wonder about how they keep the balls from hitting each other in a physical game. The game uses compressed air to shoot the two balls out of a tube almost simultaneously. They travel at the same speed so the second ball always trails the first one.
You might also wonder if the probability of the two balls landing in the same number is about the expected 1/38, assuming they the two outcomes were completely independent. At least I wondered this and annoyed the game maker with physics questions at the gaming show for much too long about it. He assured me that an independent lab did tens of thousands of spins and the probability of the two balls landing the same number is about the expected 1/38, assuming they two outcomes were completely independent.
The betting layout is mostly the same as standard roulette. With the inside bets, the player has two chances to win, but the pays are less. On the outside bets, both balls must win, but the pays are more. In addition the player may bet that both balls will land in any one number.
Rules
General Rules
- An ordinary single- or double-zero wheel is used.
- Most of the layout is the same as conventional roulette.

- Both balls must be successful for 'outside' bets to win. For example, for a bet on Red win, both balls must land in a red number.
- Either ball must be successful for 'inside' bets to win. The player will win twice as much if both balls result in a successful outcome.
- For the 'Double Ball Jackpot' bet to win, both balls must land in the selected number.
- A remote-controlled button is given to a player to activate the air gun shooting the balls.

Strategy
My advice in any game is to go for the bets with the highest expected return. In the case of a double-zero wheel, the best bet is the inside bets on one single number, at a house edge of 5.33%. The two- and three-number bets are not much worse at 5.54% and 5.89% respectively.
I would be remiss in my duties if I didn't say that the house edge in standard double-zero roulette is lower at 5.26%. However, this is only 0.07% lower than the single-number inside bet in Double Ball Roulette.

Strategy
As with any game of pure luck, all you can do for yourself is to make the bets with the lowest house edge. In this case it is the single-number inside bet, with a house edge of 2.78%. If that is too volatile for you, the double-number inside bet is not much higher at 2.99%
